DirectX - Drawing Primitives to World Space

Hello, I'm trying to simply draw a square onto the screen...I have created a custom vertex struct for each of 4 vertices, and locked them into a vertex buffer...I have followed the tutorials to draw the primitives, however, when the program executes, I can see only a portion of the square in the upper left corner of the screen (also, I have a camera set up that can move around the 3D space with mouse and keyboard commands...the square stays in the corner of screen).

Is this because the square hasn't been transformed into World Space? How do I move the square into world space? Or fix this problem...here is my code: the function to create the square is within the TerrainTwo function of graphics.cpp
